Reconstruction for middle colic artery aneurysm in a patient after thoracic and abdominal aortic aneurysm repairs

Abstract

  Middle colic artery aneurysm is a rare aneurysm of visceral arteries. Most cases of middle colic artery aneurysms are treated with endovascular coil embolization or open ligation. However, a colectomy may sometimes be required because of intestinal ischemia. We report a case in which a surgical reconstruction for a middle colic artery aneurysm using a saphenous vein graft was successfully performed in a patient after thoracic endovascular aortic repair and Y-grafting for thoracic/abdominal aortic aneurysms. Surgical reconstruction of the middle colic artery may be an alternative to the colectomy in patients with a high probability of intestinal ischemia.
